Cortex-A55 PMU support

DNovo
Offline

Hi,

I've recently acquired a development board including Cortex-A55 CPUs. However, I'm not able to access the performance monitoring counters via PAPI.
Digging further, I've seen that perfmon2 does not support the Cortex-A55 CPU at the moment. Is there any other way I could access the PMU counters from the source code?

Best,

d.

    Hi 
    Thanks for your answer. It turns out that perfmon2 is very easy to extend to support new architectures. So we've taken as bases the Cortex-A53 configuration files and replaced key parameters with information found in the Cortex-A55 reference manual. After that, we could access the performance monitoring counters from PAPI.
